There are some similarities between cryptocurrency trading and Forex in general, but of course there is a big difference in the details and particulars, the principles, basics, terminology and tools used in the analysis are almost the same.
But for me, trading in cryptocurrencies is easier, less risky and more profitable, trading in Forex carries very high risks as you can lose all your money while in cryptocurrencies it is less risky except for trading futures and using leverage.
Personally, I prefer spot trading in cryptocurrencies because it remains the easiest and safest option for beginners.
